When a leading GOP presidential candidate starts spouting Nazi-like ideology, it’s time to suspend Godwin’s Law.

Godwin’s Law, for those of you too sensible to spend time arguing online, is a rule of internet communication that goes like this: “As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1.” In other words, if two people argue on the internet long enough, one of them will compare the other to Hitler. When that happens, the discussion is over, for it’s obviously not going to go anywhere productive.

Transformer’s Unicron versus Star Wars’ Death Star: which one would win in a fight? If you say neither, you’re Hitler and/or a Nazi.

But Godwin’s Law was meant for petty arguments over nerdy topics like “Who would win in a fight: Unicron or the Death Star?”* and “Which actor was the best Batman?”* Godwin’s Law is meant to poke fun at melodramatic netizens’ use of hyperbole. It falls apart though when a person legitimately spouts political ideology similar to that of the Nazis.

Recently, leading GOP presidential candidate Donald Trump suggested forcing America’s Muslims to register with a special database and carry special identification paperwork, like the Nazis literally did to the Jews (along with other ethnic and cultural minorities).
